Subject: [PATCH 2/3] thermal: tango: Fix module autoload
Date: Fri, 14 Oct 2016 11:35:01 -0300	[thread overview]
Message-ID: <1476455702-21748-3-git-send-email-javier@osg.samsung.com> (raw)
In-Reply-To: <1476455702-21748-1-git-send-email-javier@osg.samsung.com>

If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module.

Export the module alias information using the MODULE_DEVICE_TABLE() macro.

Before this patch:

$ modinfo drivers/thermal/tango_thermal.ko | grep alias
$

After this patch:

$ modinfo drivers/thermal/tango_thermal.ko | grep alias
alias:          of:N*T*Csigma,smp8758-thermalC*
alias:          of:N*T*Csigma,smp8758-thermal
